OUR BOOK SHELF. 



Seventh Annual Report of the Geological Survey of Indiana 

 for 1875, by E. T. Cox, State Geologist, assisted by Prof. John 

 Collet, Prof. W. W. Borden, and Dr. G. M. Levette. Indian- 

 apolis 1876. 



This. is an octavo volume of six hundred pages, and contains, in 

 addition to reports by the gentlemen named, detailed reports upon 

 the geology ot a number of counties, by Dr. Moses N. Elrod, Dr. E. 

 S. Mclntire, and gentlemen connected with the survey; aieport on 

 Fossil Marine Plants by Prof. Lesquereux, and a catalogue of the 

 Flora of the Wabash Valley by Dr. Schneck. Dr. Levette has also a 

 report on the Depth and Temperature of some of the Lakes of 

 Northern Indiana. The whole forms a valuable book of reference, 

 though in regard to the catalogue, we think the species should have 

 been numbered consecutively, instead of merely numbering the spe- 

 cies of each genus.

 ume I. Edited by John Phin. [pp. 144. Illust.] New York,

 matter, not only upon the various subjects pertaining to microscopy, 

 but upon entomology and kindred sciences-, and is well worth the sub- 

 scription price, 50 cents a year, payable in advance. We welcome it
